Swing实现台球桌按时计费
前些日子我一兄弟找到我，说想让我帮他的小台球厅弄个计费软件，好家伙，就3个台还得记个费~~
超级简易。
虽然简易，但是也要登录！
先看看最终效果
上代码！！

public class Login extends JFrame{
private static final long serialVersionUID = 1L;
public Login(){
setVisible(true);
setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
//设置顶部提示文字和主窗体的宽，高，x值，y值
setTitle("***台球");
setBounds(300, 200, 300, 150);
setLocationRelativeTo(null);//居中
Container cp=getContentPane(); //添加一个cp容器
cp.setLayout(null); //设置添加的cp容器为流布局管理器
//设置左侧用户名文字
JLabel jl=new JLabel("用户名：");
jl.setBounds(10, 10, 200, 18);
final JTextField name=new JTextField(); //用户名框
name.setBounds(80, 10, 150, 18); //设置用户名框的宽，高，x值，y值
//设置左侧密码文字
JLabel jl2=new JLabel("密码：");
jl2.setBounds(10, 50, 200, 18);
final JPasswordField password=new JPasswordField(); //密码框：为加密的***
password.setBounds(80, 50, 150, 18); //设置密码框的宽，高，x值，y值
//将jl、name、jl2、password添加到容器cp中
cp.add(jl);
cp.add(name);
cp.add(jl2);
cp.add(password);
//确定按钮

jb.addActionListener(new ActionListener(){ //为确定按钮添加监听事件

return;
}

// JOptionPane.showMessageDialog(null, "登录成功");
setVisible(false);// 本窗口隐藏,

dispose();//本窗口销毁,释放内存资源
}
else{
JOptionPane.showMessageDialog(null, "用户名或密码错误");
}
}
});

//重置按钮

button.addActionListener(new ActionListener(){ //为重置按钮添加监听事件
//同时清空name、password的数据

}

图片设置
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.ImageIcon;
import javax.swing.JPanel;
public class HomePanel extends JPanel{
/**
*
*/
private static final long serialVersionUID = 1L;
ImageIcon icon;
Image img;
public HomePanel() {
// /img/HomeImg.jpg 是存放在你正在编写的项目的bin文件夹下的img文件夹下的一个图片
// icon=new ImageIcon(getClass().getResource("/img/bg.jpg"));
icon=new ImageIcon(HomePanel.class.getResource("/img/bg.jpg"));
img=icon.getImage();
}
public void paintComponent(Graphics g) {
super.paintComponent(g);
//下面这行是为了背景图片可以跟随窗口自行调整大小，可以自己设置成固定大小
g.drawImage(img, 0, 0,this.getWidth(), this.getHeight(), this);
}
}
另外需要导入两个jar包
jgoodies-forms-1.8.0-sources.jar
jgoodies-common-1.8.0-sources.jar
结束，这里就简单记录一下，后续他如果做大了，我再回来改改，收他费~
哦对了，想玩玩swing的同学建议安装一下windowbuilder插件，安装方法百度一大把。
